This powershell script gets a list of scopes and scope options from the two servers in a split scope environment. This should work from a 2008 R2 DHCP server and higher It is rough and ready, but it works. I use out-gridview , so I can copy and pate into Excel. You will need to modify the $PrimaryDHCPServer and the $SecondaryDHCPServer to your servers.

I add a property to the object, so that you can tell which scope option is from which server.
